Q. Select the outlier in the data set.\newline6,64,84,85,87,89,91,966, 64, 84, 85, 87, 89, 91, 96\newlineIf the outlier were removed from the data set, would the mean increase or decrease?\newlineChoices:\newline(A)increase\newline(B)decrease
  1. Calculate Mean: Calculate the mean of the data set: (6+64+84+85+87+89+91+96)/8=75.25(6 + 64 + 84 + 85 + 87 + 89 + 91 + 96) / 8 = 75.25
  2. Identify Outlier: Identify the outlier by comparing each data point to the mean. The number 66 is significantly lower than the mean and other data points.
  3. Calculate Mean Without Outlier: Calculate the mean without the outlier: (64+84+85+87+89+91+96)/7=85.14(64 + 84 + 85 + 87 + 89 + 91 + 96) / 7 = 85.14
  4. Compare Means: Compare the two means: The original mean is 75.2575.25, and the new mean without the outlier is 85.1485.14. Since 85.1485.14 is greater than 75.2575.25, removing the outlier increases the mean.
